To all fwkom it may concern.'

Be it 'known that l, DANIEL J'. MONIHAN, a

citizen of the `United States, residing" at 'y into a bottom Hue, or chamber` 8.v

Erie, in the county of Erie and State of Pennsylvania, have invented new and vuseful Improvements in Ovens, of which the following is a specification.

This invention relates to ovens and .consists in certain improvements in the `construction thereofas will be hereinafter fully described and pointed out in theclaims.

The oven is particularly adapted for-use with gas stoves Vand is designed to provide a more even distribution of the heat in the oven chamber than has heretofore been accomplished. v

Theinvention is illustrated in the accompanying drawings as follows Figure 1 is a front elevation of the oven, v

a part being broken away to better show construction. Y

Fig. 2 a vertical ysection in a plane from front to rear of the oven.

Fig. 3 avertical section through an end Hue of the oven. a Y 1 marks the bottom plate of the oven chamber, 2 the side walls, 3 the back wall, 4 the bottom plate of the exterior shell, `5 the side walls of the exterior shell and 6 the top wall of the shell. The bottom plate has an opening 7 which is ordinarily set over a gas burner and this opening` enters he Hue or chamber 8 communicates at its ends with a vertical Hue 9 arranged between the side walls 2 and 5. The space betweenthe walls 2 and 5 is closed at the top of the Hue 9.. by a plate 10 and openings 11 are arranged in the wall 2l in the oven chamber. a A partition 12 divides the oven chamber into an upper and lower space. This partition is double-walled and a Hue 12a is formed between these walls. Openings 13 open from the Hue 12a into the bottom space and openings 14 connect the Hue 12a with the upper space of the oven. The gases pass from the upper space through openings 15 in the side walls and downwardly between the walls 2 and 5 in a Hue 16 formed between said walls and discharge through openings 17 in the side wall above the plate 10.

This oven in a general way is similarY v Speccaticn'of Letters Patent. y Application filed `lvlovernber 25; 1'918.*`Seria1` `1`\To.26*`,96`7.

to' the oven described in patentsto George Pateiitediiiner, Y

1V. vGrraves, #1,126,753,1"Fe'b- 2,1915, and

#1,187,727 June 20, 17916. In vthe construeL tion shown yin said patents vthe partition carrying the Hue 'has'op'ening's at one edge f of the Vpartition leading from the bottom space and openings vrat the opposite 'edge of the partition'plate entering they upper spaceof t-he oven. 'The gases passing from the -wa-lls of the oven and vthence enti-rely l across the bottom space totheopenings in thepartition Yare lvery muchk .obstructed when there is material-inV the'oven'and as aresult the" oven is not uniformly. heated'. By placing the vopen-ings 13 atthe center and carrying Athe gases each -way to the openings 14 the material inthe oven does not obstruct the passage of `gases to such an extent as to interfere with uniform heat# ,ing of the oven space. l kpassage of gases approximately equal distances from both side walls tends to give a more uniform heating.

It will further benoted that the openings 11 are in a series of rows and cover a large part of the side walls of the lower compartment of the ovenfchamber'. gives a more uniform distribution of heat at all times and when the oven is obstructed by material in the oven the `openings permit of a circulation froml any part that may be unobstructed.

What I claim as new'is:-V a

V1. An oven lcomprising an oven chamber; means for introducing hot gases to the chamber; and a partition separating the chamber into an upper and lower space, sai'dpartition being in the form of a Hue with a centrally located openinginto one space and Furthermore vthe a Y This so n

ber; and a partition separating the chamber .Y v

into an upper and lower space, said parti-,

tion being inthe form of'a Hue with a centrally located opening into one space and an opening near the end ofthe partition 3.- An oven comprising an oven chamber;` y means for introducing hot gases to the chamber; anda partition separating the chamber nto'an upper and lower space, said parttion being 1n the form orn a Hue with a centrally located opening intoone space and openings at oppositeV edges of the partition into vthe other space. f4. An oven comprising an oven chamber;

Vmeans forintroducing hot' gasesto the chamber` at the ends and into the lower space of the oven; anda partition separating the oven chamber into an upper and lower space(` saidpartition being in theform of a Hue vwith a centrally located opening into the lower space.

5. Anoven comprisingan oven chamber;

means for introducing hot gases to the chamber at the ends and into the lower space of the partition into the upper space.

6.- An oven comprising an oven chamber; means for introducing hot gases to the chamber lat the ends andinto the lower space oi .the oven; and a partition separating the Aoven into an upper andr lower space,v saidV partition being in the form of a Hue with centrally located openings leading into vthe .i

lower space and openings leading from the.

Hue near its ends into the upper space.

7.' An oven comprising an'oven chamber; i

aA partition separatingthe chamber vinto an kupper and lower space, said partition being in the form ofa Hue with a centrally located opening leading Y from the Y lower space 'of the chamber and discharging to the upper space; and means for introducing hot gases from the side walls of the lower space of the chamber.

`8. An oven comprising an oven chamber;

a partition separating the oven into an upper and lower space, said partition'having a passage therein for the passage of gases from the. lower space to the upper space;v vand means for introducing gases to 4the lower ing openings through opposed walls of the chamber and said openings arranged and proportioned to distribute the gases as introduced tothe oven over a lmajor portion of kspace of the chamber, said means comprisy said opposed walls, the entrance to the pas- .l

sage in the partition being remote fromthe opposed walls.

In testimony whereof I have Vhereunto set my hand.
